WATER-CLOSET BOWL.

Spccifieatiers Patent. l Patent d ME 3@ 191% Application filed August12, 1915. Serial No. 45,142.

To all whom it may concern Be it known that I, JOHN T. BRnDsHAw, acitizen of the United States, resldmg at Trenton, in the county ofMercer and State of New Jersey, have invented certain new and usefulImprovements in Water-Closet Bowls, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to water closet bowls, and particularly to thattype of bowl having a flushing rim.

The general object of my inventlon is to so form the bowl that the rimshall be sanitary at those parts of the rim which are particularlyliable to become soiled, and 1n th1s connection provide means foreffectively flushing those parts of the rim.

A further object is to so form the bowl and the flushing rim that thebowl will be flushed for its full diameter and for its full height. Andanother object is to flush both the back and front of the bowl byfan-like sheets of water projected horizontally from opposite terminalportions of the rim. 7

A further object is to so form the bowl that the front wall shall berelatively thin so that only a very small surface likely to soil ispresented.

Still another object is to attain the advantages above referred towithout increasing the cost or difliculty of making the bowl but on thecontrary reducing the cost.

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical section of a closet bowl constructed inaccordance with my invention; Fig. 2 is a top plan view; Fig. 3 isatransverse section of the construction shown in Figs. 1 and 2; Fig. 4 isa vertical fragmentary section of the rear end of a bowl; Fig. 5 is avertical section of the forward end of a modified form of bowl; Fig. 6is an enlarged fragmentary section at the forward end of the bowl, thesection being taken through the flushing rim.

In the ordinary closet bowls the parts of the bowl most liable to besoiled are the front of the bowl and the rear thereof. To obviate this,bowls have been devised in which the forward portion of the bowl isforwardly extended to receive the urine, and the rear.

end of the bowl is rearwardly offset or extended to form a continuationof the seat opening. No means however have been provided for efficientlyflushing the vertical inner surfaces of the front and rear walls ofthese offsets, except to some extent beneath the rim of the bowl. Theseobjectionable features are avoided by the construction now to bedescribed.

7 The bowl 2 is of any usual or'suitable design, and except in thedetails hereafter pointed out may be of any construction. Of course thebowl is to be made of earthenware, porcelain, or like material. The bowlis shown as formed with the usual legs 3 and 4 of the siphonic dischargeand with the usual distributing chamber 5.

As shown in Fig. 2, the bowl is substantially elliptical in plan and hasthe gener ally elliptical opening 6. The sides of the bowl are thickenedso as to form overhanging rim portions 7, these rim portions beingrelatively deep. At the front of the bowl, however, these thickenedportions terminate, as at 8, and merge into a relatively thin andshallow rim 9 which very slightly overhangs the body of the bowl. Thefaces 8 of the rim portions 7 are disposed at a slight inclination tothe vertical. Inasmuch as the rim portions 7 terminate at 8, anextension 10 of the seat opening 6 is formed. At the rear, the rimportions 7 terminate at 11 and extend upward and rearwardly and mergeinto the relatively shallow or thin slightly overhanging rim 12.

A waterway 13 extends around the rear end of the bowl and is incommunication with the chamber 5. This waterway or passage extendsthrough the length of each rimportion 7, as shown by dotted lines Fig.2. The lower face of each rim portion is formed with elongatedperforations 14 for the discharge of water into the bowl. The end face 8of each rim portion 6 is also perforated so that jets of water aredischarged horizontally across the surface of the front end of the bowlbelow the rim 9 and also downwardly at a slight angle to the horizontaL-The rear end face of each rim portion is also perforated so that jets ofwater are discharged across the face of the rear end of the'wall 15below rim 12. Inasmuch as the terminal faces merge gradually into theunder faces of the rim sections, the jets from the ends of the rimsections will be projected at different angles so that a fanshaped sheetof water will be ejected across the front and rear end faces of thebowl.

In Figs. 4 and 5 I show a slightly modified form of my invention asapplied to those closets whose bowls are formed with lips at theirforward or rear ends, or both. In these closets the side rim sections"1' merge at the forward ends into the rim 9? slightly, and the forwardends of the rim portions 7 a are each provided with a slot 14discharging a fan-shaped jet,not only across the inner face of the lipbut upward against theoverhanging flange or rim 9*. The rear lip 12 isalso raised above the general level ofthe top edge of the bowl, and thejet opening 14 discharges upward against the rim 12*. 'It is to be notedthat in my con struction the forward portion of the bowl is notextended, but the extension 10 of the bowl opening is formed by reducingthe thickness and depth of the rim. By thinning the rim at the front, Ireduce the surface subject to contamination when the I closet is used asa urinal.

a sides of'a forward extension of thebowl The ordinary closet is flushedover the top of thebowl all the way around, necessitating a waterwayeither within or on top of the bowl and this reduces the size of thebowl opening. A bowl constructed in accordance with my invention can beflushed I in every part for thepentire circumference of the bowl and tothe full height of the bowl between the flushing rims.

i The bowl is simple in design and can be cheaply made.

. Having thusdescribed 'my invention, what I claimis: I

1. A closet bowl having on each side an overhanging flushing rimportion, the forward ends of the rim portions terminating at each sideof the bowl opening, the for ward ends of the rim portions forming theopening and being perforated to: cause the discharge of watertransversely across the I Copies of this patent may be obtained for rfront part of the bowl between the ends of v the rim portions, saidforward wall having a relatively thin and slightly overhanging rim. Y rV 2. A closet bowl having on eachside an overhanging flushing rimportion, the forward and rear ends of the rim portions terminating ateach side of the bowl opening and said ends defining and forming thesides respectively of the forward and rear extension of the bowl openingand being perforated to cause the discharge of water transversely acrossthe front and rear walls of the bowl between the ends of the rimportions, said forward and rear walls beacross the wall and downwardacross the wall.

4:. A closet bowl having on each side an overhanging rim portion, theforward and rear ends of the rim portions terminating at each side ofthe bowl opening and defining the sides of a forward extension of thebowl opening, the forward and rear Walls of the bowl between theterminal ends of 'the flushing rim portions being upwardly and forwardlyextended to form lips each of said lips having a relatively thinsllghtly overhanging rim, the ends of said firstnamed' rim portionsbeing perforated to cause the discharge of water transversely across thefront and rear walls of the bowl, between the ends of the rim portionsand upward against the overhanging rim of said lips. v

In testimony whereof I hereunto aifix my signature in the presence oftwo witnesses.
